SOCKET FOR DlPPER-HANDLES.

SPECIFICATION forming part of Letters Patent No. 509,173, dated November21, 1 893.

Applicationfiled January 28, 1893- Serial No. 460,012- (No model.)

To aZZ whom it may concern.-

Be it known that I, GEORGE W. KNAPP, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Sockets for Dipper-Handles, of which thefollowing is a specification.

This invention relates to an improvement in sockets for dipper handles,and has for its object to provide a socket struck up from a singleblank, which shall be cheaper to manufacture, more durable in wear andwhich shall present a neater and consequently more salable appearance,than sockets generally in use.

The invention is illustrated in the accompanying drawings in which-Figure 1, is a view of the circular blank from which the socket isstruck. Fig. 2, is a vertical-section of the socket illustrating thefirst step of procedure in its manufacture, in which the blank is struckinto the flanged, cylindrical shape shown. Fig. 3, is a viewillustrating the'second step, which consists in cutting out the closedend, a, of the shank of the blank as shown in Fig. 2. Fig. 4, is a Viewillustrating the third step, which consists in expanding the open end,a, of the shank, to make it taper toward the flange b. Fig. 5, is asection of the finished socket. Fig. 6, is a view of the finishedarticle in position upon the bowl of the dipper.

Heretofore it has been the custom generally, when attaching wood handlesto dippers and analogous articles, to use a cast iron socket, having around shank, to receive the end of the wood handle, and a flange throughwhich the rivets are driven to secure said socket to the bowlof thedipper. This socket is more or less unsightly, besides beingcomparatively expensive to manufacture and heavier than is desirable. Ithas too that fault inherent to cast iron,it is brittle.

To provide a socket which shall combine the desirable qualities, withoutthe faults above enumerated, is the object of this invention.

In the drawings, the letter, A, Fig. 1, designates the circular blank,from which the socket is struck; B, the shank of the socket which isformed when the blank is struck by the die, and, b, is the flange,which, in the finished article is riveted to the bowl of the dipper.

In making the socket, several steps are employed: first,striking theblank into the form shown in Fig. 2, of the drawings, which iscylindrical and has a flange at one end, the other end being closed by apart, a; second, opening the closed end, by punching. out the part a;third, expanding the cylindrical shank B, so as to make it taper towardthe flange; fourth, bending the flange to a proper angle with respect tothe axis of the cylindrical shank, so that the handle, when inserted inthe shank of the socket, will have a proper inclination with respect tothe bowl of the dipper, and trimming the flange, and punching the rivetholes therein, leaving it in a finished condition.

After securing the socket to the bowl of the dipper, the whole istinned, so thata close tight joint is made between the flange of thesocket and the wall of the dipper.

The socket though light, is, on account of its tubular shape, verystrong, and yet neat in appearance.

Although preferable, the tapering form of the socket is not absolutelyessential to the spirit of my invention.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combination of a dipper bowl; a wooden handle; asheet-metal socket for attaching the handle to the bowl and comprising aseamless, tubular shank open from end to end and having at one end anintegral angularly-disposed flange provided with rivet holes and withflat edges so that the concave surface of the said flange is in contactwith the surface of the bowl; and rivets securing the flange to thebowl, as shown and described.

In testimony whereof I affix my signature in the presence of twowitnesses.

GEORGE W. KNA-PP.
